rarest eine SASH WEIGHT.

Application led September 14, 1925.

Our present invention relates generally to sash weights, and has for itsprimary object the elimination of certain practical or operatingdisadvantages due to the structure and methods of formation nowenjploycd. lt is well known that in casting sash weights according tothe present method, the eye or hole is left rough, frequently withcutting ridges where the mold sections join and also with square edgesor shoulders, all of which soon abradc the sash cord in practice withthe result that it quickly breaks and frequent repair becomes necessary.

lt has already been proposed to cast separat-e eyes in sash weights, butthis adds considerably to the cost thereof and great diiiiculty isexperienced in arranging the eyes in the molds so that they areuniformly set in the finished weights.

Our invention proposes to eliminate the disadvantages in the aboverespects by forming the smaller or bore end of the weight within ahollow cup or jack-et which may be set firmly and solidly in a mold andwhich becomes a part of the weight to be withdrawn from the mold withthe weight and more or less permanent depending` upon the material ofwhich the cup or jacket is constructed. This cup or jacket will havemeans adapted to form an eye through the weight and is preferably astamped product formed of sheet metal, paper or other materialsuiiiciently strong to last at least until the cast metal sets and of aoharacter presenting a smooth inner face so that the surface of thefinished weight through and around its eye will likewise be smooth andwithout abrasive corners, projections and the like.

In the accompanying drawing, which illustrat-es our present invention,

Figure l is a side view of the cup or jacket proposed by our invention,

Figure 2 is a vertical section taken centrally therethrough,

Figure 3 is a sectional view through a mold in which the sash weightsare formed in accordance with our invention, and

Fioure 4 is a side view of a iinished sash weight.

Serial No. 56,328.

Referring now to these figures, and particularly to Figure 4, ourinvention proposes a sash weight l0 having around its upper smaller enda jacket 1l formed of said smooth material with an integral tubularportion l2 thereof extending transversely thereof and forming thecord-holding bore or eye of the sash w-eight. This jacket is initiallystamped or otherwise suitably formed of the hollow shape shownespecially in Figure 2 wherein its transverse tubular portion 12 may beplainly seen. The jacket or cup l1 is associated with the sash weightwhen the latter is formed in a mold and is, at this time, lled with themetal which when set in the mold, constitutes the weight. Moreover, thejacket or cup thus forms a part of the sash weight anda part which ismore or less permanent, depending upon the material of which the jacketis formed. lf constructed of sheet metal, the jacket endures, and anexternal smooth surface is, of course desired, while if a less durablematerial, such as paper is used, it must have a smooth inner face andmust -of course be suiiiciently strong to retain the molding andsmoothing influence until the cast metal has set.

In accordance with our improved method` the cup or jacket 11 is invertedin the mold drag 13 as shown in Figure 3 within the base of the moldcavity, so that by placing the cope 14 on the drag, the molten metal mayb-e poured into the series of cavities without difculty so that it willrun into and fill the several cups or jackets ll.

It is thus obvious that irrespective of the material of which the cup orjacket ll is formed, it constitutes a more or less permanent part of the'sash weight so that after the metal has set, and the weights areremoved from the mold, the cup or jacket, or what is left of the cup orjacket, is removed with each weight.

In this way, our invention avoids the addition of any difficulties ordisadvantages to the molding of the weights, and at the same timeprovides for the elimination of the disadvantages first above mentionedin sash weights as constructed at the present time as Well as in methodsof manufacture Which have been used up to the present time with theobject in view of elimination of rough edges adjacent to the eye of thesash 5 Weight.

Ve clamz A sash Weight comprising a jacket having an integral, tubular,eye portion, and an integral casting filling said jacket and tubular eyeportion. 10 In testimony whereof We have aiiXed our signatures.
